Application August 4, 1933, Serial No. 683,709 2Claims. (o1.'242-124) The present invention relates to a spool and more particularly to a spool especially adapted for use in connection with dyeing machines.

One of the objects of the present invention is 8 to provide a dyeing spool which consists of a few number of parts, simple to assemble and practically indestructible.

The present type of dyeing spool generally used in the industry comprises a tubing forming 10 the barrel, on the ends of which there is securely fastened by expanding and pressure methods, disk-shaped heads. It has been found that due to the strain and the weakening of the tubing from the expansion it becomes ripped and otherl5 wise damaged adjacent the heads. The present invention contemplates the construction of a dyeing spool'which will not only overcome this objection but the parts of which may be used for repairing the damaged spool.

20 In the accompanying drawings forming a part of this application and in which corresponding parts are designated by similar reference numerals,

Figure l is a front elevational view partly in 25 section of the new type of spool,

30 Figure 4 is a fragmentary front elevational view partly in section of the present type of spool now in general use in the industry,

Figure 5 is a disassembled view partly in section illustrating the manner in which a portion of the 35 length of the damaged barrel of the old spool shown in Figure 4 and the head thereof is assembled with certain parts of the new spool to permanently repair the old spool,

Figure 6 is a fragmentary vertical sectional 40 view of the repaired spool illustrating the manner in which the different parts of the spool illustrated in Figure 1 are used to repair the type of spool illustrated in Figure 4, and,

Figure 7 is a fragmentary end view of Figure 6. 45 In the accompanying drawings forming a part of this application wherein there is shown for the purpose of illustration a preferred embodiment of the invention, and referring more particularly to Figure 1, the reference numeral 8 generally desig- 50 nates a solid cast disk-shaped head which is provided with a centrally-disposed screw-threaded aperture l and a flange l2. Into the centrallydisposed screw-threaded aperture I0 of the heads 8 there is screw threaded a bushing [4 having a 55 bore 16. The bushings l4, by means of heavy pressure, are forced into the ends of the barrel I8 until the ends thereof firmly abut the shoulder 20 of each of the bushings. As is clearly illustrated in Figure 1, the bushings 14 extend into the barrel [8 for a length thereof, providing a reinforcement adjacent the disk which is subjected to the greatest stress. In this assembled position, the barrel is then placed under a drill press and a plurality of apertures 25 are bored therein.

In Figure 4, there is illustrated the old type of spool which is now in general use in the industry and it has been found that this type of spool due to the heavy stresses adjacent the heads thereof and because of excessive use of ex- 15 panding methods in assembling the barrel in the heads serve to weaken the material considerably, causing the ends of the barrel 24 adjacent the head to split.

Because of the damaged head and barrel of the old spool it has been heretofore necessary to buy a complete new spool and it is therefore one of the objects of this invention to construct a spool, the parts of which with slight changes in the parts of the damaged spool, may be used in con- 25 junction therewith for repairing the old damaged spool. The only difference being that the head of the spool illustrated in Figure l is built with a solid casting while the head used in repairing the old spools consists of two parts, namely, the rebuilt head of the old spool and a screw threaded disk which is secured thereto.

When the barrel of the old spool as illustrated in Figure 4, is damaged at the ends thereof because of the splitting heretofore described, it is placed in the lathe and the expanded ends are cut back beyond the split portions thereof which length is usually from one-half inch under ordinary conditions to a maximum of one to three inches. The head 26 of the damaged spool is then placed in the lathe and the hub or shoulder 28 turned off leaving a simple disk 26' 'as illustrated in Figure 5. To the disk 26 there is securely fastened by means of rivets 40, a replacement head 42 having a centrally disposed aper- 45 ture 44, and a shoulder 46. The damaged portion of the barrel 24 is then bored from the disk, and the disk and replacement head are threaded.

In order to compensate for the damaged length of the barrel 24 which was cut away and at the same time provide a reinforcement at the points of greatest stress of the spool there is provided a bushing 32 which is turned and threaded to fit the barrel 24 and the heads 26'.

The outside of the bushings 32 for a portion of their lengths 34 are finished to a driving fit and and replacement head are then secured onto. 7

the bushing to form a repaired spool of exactly the same dimension as the old damaged spool. P It is to be noted in this connection that the bush- .7

ing 32 used in repairing the old spool is the same type as the bushing 14 of the new spool with the exception of course, that the shoulders 36 of the bushing 32 are longer than the shoulder 20 to compensate for the length of the damaged portion of the barrel 24 cut away.

7 It will thus be seen, as illustrated in Figure 6, that by employing the same parts of the improved spool as illustratedin Figure 1 with the exception of the cast head 8, that a portion ofthe tubing or barrel 24 and the head 26 of the old spool may be used to permanently repair the old spool.

It will thus be seen that there is provided a dye- 7 said bushings.

ing spool which is reinforced at the points of greatest stress during use, the parts of which with a slight variation in thehead may be used in the permanent repair of inferior spools now in use.

While there is shown for. the purpose of i1lus-' I tration only. one preferred embodiment of the invention, it is to be understood that it'is capable of various changes and modifications without departing from the spirit thereof and it is intended therefore that only such limitations shall be im-. 10 posed thereon as are indicated in the prior art or in the appended claims.
